“I don’t know. I wish I knew the answer to [how to replace Jozy]. It’s going to be interesting to see how the coaches adjust," Donovan said. "Whether you leave[Clint Dempsey] up there by himself or you play another forward with him. I’m sure they’ve watched the Portugal tape over and over and they’ll have an idea how to beat them. At the end of the day, it’s still 11 v. 11 but there’s no question that the team will miss Jozy.”

But no matter who fills in for Altidore, Donovan is confident that the U.S. can earn the win needed to get through to the knockout round for the second consecutive tournament.

“It’s amazing how results change things and even one goal changes things,” said Donovan. “That goal by John Anthony Brooks coupled with Portugal losing, now you look at a scenario where you win the game then you’re through against a somewhat beaten up Portuguese team. It’s amazing how it is coming together, but it can go the other way too. You have to be prepared and it’s going to be a fascinating match.”
